Question

Quizplus · Accepted Answer

A fasting blood glucose level greater than 126 mg/dl is diagnostic of diabetes. "Fasting" is defined as no caloric intake for at least 8 hours. A glucose tolerance test that returns to normal in 2 hours is a normal finding. The presence of ketones in the urine does indicate that the body is using fat for energy, but this could be from several causes. Urine glucose testing is not reliable. A casual blood glucose test should be less than 200 mg/dl.
